ICP Furnace Control Board Kit for RGS102LDAB0AAA — OEM Ignition Control | Ships Today

Overview

This is the genuine OEM control board kit (part 1183618) for the ICP / Tempstar / Heil RGS102LDAB0AAA gas furnace. The integrated furnace control board is the brain of the system: it manages the ignition sequence, sequences the inducer and blower, monitors the safety limit and flame-sensing circuits, and reads thermostat calls. A failed board causes no-heat, blower problems, fault-code lockouts, or a completely dead furnace. This kit ships with the board and required mounting/wiring components for a complete replacement.
